Definitions

  • the present invention relates to the field of passive safety of commercial vehicles or particulars may be subjected to frontal shocks applied in particular to the cooling cassette fitted to each commercial vehicle.
  • the figure 1 represents the front part of a chassis 1 of a motor vehicle intended to carry the power unit, not shown, of this vehicle and comprising in particular two longitudinal members 2 arranged on the right and left sides of the vehicle symmetrically with respect to a longitudinal median plane of the vehicle.
  • the cooling cassette 3 can be housed and fixed in a rigid frame 5 of generally rectangular shape, the two sides or substantially vertical pillars 6 are fixed, for example by welding, to the front ends of the two longitudinal members 2.
  • Some motor vehicles have their chassis equipped with cradle extensions.
  • the figure 3 represents a side view of the front part of the chassis 1 of the vehicle not including cradle extensions, the front cassette with cooling cassette 3, fan assembly 4 and rigid frame 5, being shown in solid lines at a normal position of use.
  • An object of the invention is to provide a solution for preventing the spill of the cooling cassette, stabilize the behavior of the spars and, where appropriate, its support frame of the front of the vehicle during a frontal shock.
  • the vehicle comprising a frame with two front longitudinal members, a powertrain carried by the frame, and a cooling cassette carrying a moto-fan unit attached to the ends of the two side members perpendicular to them, is characterized in that the cassette is provided with at least one frontal shock absorbing element which the cooling cassette can undergo, extending towards the rear of the vehicle in a free space between the cassette and a part of the powertrain and having a rear free end disposed with play opposite the part of the powertrain so that in the beginning of the frontal impact the shock absorbing element bears on the part of the powertrain to stop the recoil of the cassette. cooling and that this element then compress longitudinally with the two longitudinal members during the continuation of the shock to allow the cooling cassette to move back.
  • the cassette is provided with at least one frontal shock absorbing element which the cooling cassette can undergo, extending towards the rear of the vehicle in a free space between the cassette and a part of the powertrain and having a rear free end disposed with play opposite the part of the powertrain so that in the beginning of the
  • the shock absorbing element is located in the lower part of the cooling cassette.
  • the shock absorbing element is in the form of a compressible bar extending longitudinally to the vehicle.
  • the rear end of the shock absorbing element comprises a flat end face intended to bear on a flat face of the part of the powertrain during the frontal impact.
  • An anti-slip finger or pin may be provided on the bearing face of the power train portion to engage a conjugate opening in the rear end of the shock absorbing member during a shock. front.
  • the flat end face of the shock absorbing element is substantially vertical.
  • the cassette is housed in a generally rectangular rigid support frame whose substantially vertical sides are respectively fixed to the two longitudinal members and the shock absorbing element is attached to the lower horizontal side of the support frame and in the center of this side. .
  • the shock absorbing member may be metal, such as steel or aluminum, or a plastics material that may be molded with the support frame.
  • the frame 5 intended to receive and support the cooling cassette 3 shown in phantom has the same general rectangular shape of the frame of the prior art and does not in this case have an upper longitudinal side extending transversely to the vehicle, but it is understood that such a side or traverse may be present to maintain the cooling cassette.
  • the rigid frame 5 comprises a shock absorbing element 7 secured to the longitudinal and horizontal lower side 8 of the frame 5 and extending in the longitudinal direction of the vehicle parallel to the two longitudinal members 2 being disposed in a free space between the cassette 3 and a part of the powertrain.
  • the shock absorbing element 7 is thus fixed by one of its ends 7a to the lower side or cross member 8 of the frame 5 perpendicular thereto, projecting towards the rear of the vehicle and at its opposite free end. ending with a flat face 7b which can bear, during a frontal impact, on a corresponding bearing face 9a of the power unit 9 of the vehicle carried by the front frame part thereof, the bearing face 9a which may belong to the oil pan of the power train 9.
  • the flat rear end face 7b of the shock absorbing element 7, preferably occupying a substantially vertical position, is normally located at a certain distance or clearance determined relative to the bearing surface 9a of the power unit 9 and , preferably, this distance is greater than the deflections of the motor to avoid all contact between the power train 9 and the rear end of the shock absorbing element 7.
  • the rear support surface 7b of the element 7 is part of a rigid plate 10 integral with the end of the element 7 perpendicular to it.
  • the element 7 may also comprise a second lower plate 11 extending perpendicular to the plate 10 or being inclined downwardly relative thereto so as to bear, in a frontal impact, on a face corresponding support 9b of the powertrain 9 and located below the support face 9a.
  • An anti-slip finger or pin may be provided on the bearing face of the power train portion to engage a conjugate opening in the rear end of the shock absorbing member 7 at a frontal shock to prevent any phenomenon of escape of the rear end of the shock absorbing element 7 relative to the bearing surface of the powertrain.
  • the element 7 is constituted by a parallelepipedal bar compressible in its longitudinal direction and fixed at the center of the lower horizontal side 8 of the frame 5 being located in the median plane of this frame perpendicular thereto.
  • the rigid frame 5 may be metallic with its two vertical sides or pillars 6 obtained in a conventional manner by welding of various previously formed sheet metal parts and its horizontal lower side 8 forming a cross member may be produced by an aluminum profile of open section or of section closed type square or eight.
  • the frame 5 can be made of a rigid plastic material.
  • the shock absorbing element 7 may be fixed by welding, screwing, or even by bonding to the cross member 8.
  • the shock absorbing element 7 can be obtained by molding with this frame.
  • the materials used for the shock absorbing element 7 and which depend on the level of effort required during the frontal impact may be metallic, such as steel or aluminum, but also plastic materials .
  • this element may be shaped like a ribbed parallelepiped box that can compress longitudinally during a frontal impact.
  • the shock absorbing element can be integral directly with the cassette when molding it.
  • shock absorbing element in the central part of the lower crossbar 8 of the frame 5 provides an effective anti-overflow function of the support frame of the cooling cassette independently of the impact location of the impact to this frame , but an off-center implementation of this element is quite conceivable. Moreover, it is also possible to implant several shock absorbing elements in different locations of the rigid frame 5, both on the lower or upper cross member, if present, as on the vertical pillars 6 of this frame.
  • the invention thus effectively limits the spill of the lower part of a front facade of a motor vehicle through the use of an additional support formed by the shock absorbing element which increases the capacity of impact energy absorption of this facade during the continuation of the shock when the facade backs against the powertrain of the vehicle.
  • the faces 7b and 9a abut against each other of the shock absorbing element 7 of the power unit 9, because of their stability, provide good compression of the element 7.
